I’m the Female Lead’s Terrible Sister-in-Law [Quick Transmigration]

Only after Jiang Sulan died did she learn that she was the awful sister-in-law of a saintly heroine. But she refused to accept it! Why should the heroine sacrifice her and her family's interests to satisfy her own saintly impulses? Her resentment kept her from reincarnating, and by a twist of fate, she was recruited by a System. She had to play the awful sister-in-law in various worlds. In return, she earned Awful Points. Once her Awful Points were maxed out, she could return to her own previous life. After receiving the backstory for each world, Jiang Sulan gritted her teeth. Play an awful sister-in-law? Did she need to act? She already was one! 1.

All the "male and female leads" are characters in bizarre novels. Don't project them onto real people. The values in the story don't represent the author's own. Please don't go around attacking people, thank you. 3. A light, feel-good power fantasy set in a completely fictional world. Don't take it too seriously. Theme: Wherever you are, be a good person and do the right thing
